With suggested prices of $330 for the Ryzen 1700 and $400 for the 1700X, a lot of users are more curious about the performance of these two chips, especially with some sites reporting almost equal performance when these chips are overclocked. [H]ard|OCP tested both of these chips at the same clock speeds to see what performance differences there are between the two. As it turns out the only test which resulted in delta of 1% or more was WinRAR, all other tests showed a minuscule difference between the X and the plain old 1700. They are going to follow these findings up with more tests, once they source some CPUs from retail outlets to see if there are any differences there.
"So there has been a lot of talk about what Ryzen CPU do you buy? The way I think is that you want to buy the least expensive one that will give you the best performance. That is exactly what we expect to find out here today. Is the Ryzen 1700 for $330 as good as the $400 1700X, or even the $500 1800X? "

It was just announced to backers and the public that the System Shock reboot from Nightdive Studios has moved from Unity to Unreal Engine 4 and they have a pre-alpha video that shows off what that will look like. The reasoning they gave was perhaps poorly worded, suggesting that this is because the choice was solely to make the game look good in the console version. They gave backers, such as myself, reassurance that "PC is the main target for everything we do" and that the console version was already planned in Unity. Rock, Paper, SHOTGUN feels the change makes the quality of the visuals better, but perhaps not as true to the original as the previous example they showed using Unity. Check out the pre-alpha video below to see for yourself.
"In this matter at least, I am confident my sanity is unaffected. For as well as an apparent shift in its art direction to something more traditionally sci-fi/horror, SSR has hopped from Unity to the Unreal engine, resulting in a very different-looking game."

Wave goodbye to your old docks as they sail away thanks to a thunderstorm. The Register reached out to Dell, HP, Lenovo and ASUS about the rumours that the docking station will be a thing of the past and all but the latter responded. It seems the vendors feel that as USB 3.1 and Thunderbolt 3 have united under the Type-C plug it is time to cover up that slot in the bottom of your PC and use a wire to connect you to docks. Lenovo will also persist with their WiGig docks, for those who don't want to have to remember to 'undock' a cable. Their post also has some tidbits on some of the features to expect on laptops from these three companies, so check it out for more info.
"When you shop for PCs this year your theme tune may well be “Ding, dong, the dock is dead” because now that USB 3.1, USB-C connectors and Thunderbolt all play nicely together there's much less need for dedicated hardware to connect a laptop to peripherals."

Tagged: qualcomm, OCP, microsoft, falkor, centriq 2400, azure, arm, 10nm
Last December Qualcomm announced plans to launch their Centriq 2400 series of platforms for data centres, demonstrating Apache Spark and Hadoop on Linux as well as a Java demo. They announced a 48 Core design based on ARM v8 and fabbed with on Samsung's 10nm process, which will compete against Intel's current offerings for the server room.
Today marks the official release of the Qualcomm Falkor CPU and Centriq 2400 series of products, as well as the existence of a partnership with Microsoft which may see these products offered to Azure customers. Microsoft has successfully configured a version of Windows Server to run on these new chips, which is rather big news for customers looking for low powered hosting solutions running a familiar OS. The Centriq 2400 family is compliant with Microsoft's Project Olympus architecture, used by the Open Compute Project Foundation to offer standardized building blocks upon which you can design a data centre from scratch or use as an expansion plan.
Enough of the background, we are here for the specifications of the new platform and what can be loaded onto a Centriq 2400. The reference motherboard supports SOCs of up to 48 cores, with both single and dual socket designs announced. Each SOC can support up to six channels of DDR4 in either single or dual channel configurations with a maximum of 768GB installed. Falkor will offer 32 lanes of PCIe 3.0, eight SATA ports and a GbE ethernet port as well as USB and a standard 50Gb/s NIC. NVMe is supported, one design offers 20 NVMe drives with a PCIe 16x slot but you can design the platform to match your requirements. Unfortunately they did not discuss performance during their call, nor any suggested usage scenarios. We expect to hear more about that during the 2017 Open Compute Platform US Summit, which starts today.
The submission of the design to Open Compute Project ensures a focus on compatibility and modularity and allows a wide variety of designs to be requested and networked together. If you have a need for HPC performance you can request a board with an HPC GPU such as a FirePro or Tesla, or even drop in your own optimized FPGA. Instead of opting for an impressive but expensive NVME storage solution, you can modify the design to accommodate 16 SATA HDDs for affordable storage.
Qualcomm have already announced Windows 10 support on their Snapdragon, but the fact that Microsoft are internally running Windows Server on an ARM v8 based processor is much more impressive. Intel and AMD have long held reign in the server room and have rightfully shrugged of the many times in which companies have announced ARM based servers which will offer more power efficient alternatives. Intel have made huge advances at creating low power chips for the server room; AMD's recently announced Naples shows their intentions to hold their market share as well.
If the submission to the OPC succeeds then we may see the first mainstream ARM based servers appear on the market. Even if the Windows Server instances remain internal to Microsoft, the Centriq series will support Red Hat, CentOS, Canonical and Ubuntu as well as both GCC and LLVM compilers.
(click to seriously embiggen)
ARM may finally have reached the server market after all these years and it will be interesting to see how they fare. AMD and Intel have both had to vastly reduce the power consumption of their chips and embrace a diametrically opposite design philosophy; instead of a small number of powerful chips, servers of the future will consist of arrays of less powerful chips working in tandem. ARM has had to do the opposite, they are the uncontested rulers of low powered chips but have had to change their designs to increase the processing capabilities of their chips in order to produce an effective product for the server room.
Could Qualcomm successful enter the server room; or will their ARMs not have the necessary reach?

Tagged: VR, steamvr, LG
While SteamVR is practically synonymous with the HTC Vive, Valve intends it to be an open platform with multiple OEMs. At this year’s Game Developers Conference, GDC 2017, LG was showing off one of their prototypes, which the folks at Adam Savage’s Tested got some time with. The company repetitively said that this is just a prototype that can change in multiple ways.
There are some differences between this and the HTC Vive, though. One change that LG is proud of is the second app button. Apparently, the company found that developers liked to assign buttons in pairs, such as a “forward” button to go along with a “back”. As such, they added a second app button, and placed all three above the touchpad for less accidental presses. The weight distribution is, apparently, also adjusted slightly, too. The difference that Tested seems most interested in is the pull forward and flip up hinge holding the mask, allowing the headset to be moved out of the way without fully taking it off the head, and for it to be easily moved back into place around glasses. (Thankfully, I’m far-sighted, so I can just take off my glasses when I use my Daydream headset, which I assume holds true for other VR devices.)
It’s unclear when it will come to market. Tested speculated that it could happen sometime later this year, which would put it just before when we expect the HTC Vive 2, but... speculation.

Tagged: ryzen, overclocking, gskill, ddr4, AM4
G.Skill recently announced two new series of DDR4 memory geared towards AMD’s new AM4 platform and Ryzen CPUs. The FORTIS series comes in kits up to 64 GB at 2400 MHz while the Flare X series features kits up to 32 GB at 3466 MHz.
The FORTIS series come in black with graphics on the sides. At launch, there will be kits in 16 GB, 32 GB, and 64 GB capacities clocked at 2,133 and 2,400 MHz. These kits run at 1.2V.
Flare X reportedly uses “carefully selected” IC chips that have been tested and validated for the AM4 platform and Ryzen processors. These kits run at 1.35V out of the box and come in 16 GB, 32 GB, and 64 GB at 3200 MHz with 14-14-14-34 timings or in a 16 GB (2x8GB) kit clocked at 3466 MHz with 16-16-16-36 timings.
It is worth noting that Ryzen officially supports memory up to 3200 MHz without needing to overclock the bus speed using one of eight memory straps/dividers (this is apparently a limitation of the UEFI and not Ryzen's memory controllers). In order to take advantage of DDR4 with higher clocks, you will need to overclock the base clock (which is made easier/possible on motherboards with external clock generators). G.Skill showed two examples using a Ryzen 7 1700 and an Asus Crosshair VI Hero motherboard where they got a 4x16GB kit clocked at 3467MHz (16-16-16-36 CR1) by setting a 25.4 x multiplier and 118.16 MHz bus speed. The other example was DDR4 at 3200 MHz with a multiplier of 28.4 and 119.99 MHz bus speed. It is interesting that they were able to push the bus speed that high while maintaining stability. G.Skill posted two CPU-Z validation screen shots on its news announcement.
G.Skill did not announce pricing, but it did state the new memory kits would be available later this month. Looking around on Newegg, it seems some of the lower speed kits with 4GB DIMMs are available right now but the new kits with higher clocks and 8GB and 16GB DIMMs are not available yet. The less exciting Fortis series does appear to be available though with a 2x8GB 16GB DDR4-2400 priced at $124.99. Even the Fortis series isn’t fully launched yet though since the 2x16GB and 4x16GB kits aren’t listed.
Introduction and Specifications
The G533 Wireless headset is the latest offering from Logitech, combining the company’s premium Pro-G drivers, 15-hour battery life, and a new, more functional style. Obvious comparisons can be made to last year’s G933 Artemis Spectrum, since both are wireless headsets using Logitech’s Pro-G drivers; but this new model comes in at a lower price while offering much of the same functionality (while dropping the lighting effects). So does the new headset sound any different? What about the construction? Read on to find out!
The G533 exists alongside the G933 Artemis Spectrum in Logitech’s current lineup, but it takes most of the features from that high-end wireless model, while paring it down to create a lean, mean option for gamers who don’t need (or want) RGB lighting effects. The 40 mm Pro-G drivers are still here, and the new G533 offers a longer battery life (15 hours) than the G933 could manage, even with its lighting effects disabled (12 hours). 7.1-channel surround effects and full EQ and soundfield customization remain, though only DTS effects are present (no Dolby this time).
What do these changes translate to? First of all, the G533 headset is being introduced with a $149 MSRP, which is $50 lower than the G933 Artemis Spectrum at $199. I think many of our readers would trade RGB effects for lower cost, making this a welcome change (especially considering lighting effects don’t really mean much when you are wearing the headphones).Another difference is the overall weight of the headset at 12.5 oz, which is 0.5 oz lighter than the G933 at 13 oz.

Microsoft is currently working on a solution and the incident count on Down Detector seems do have dropped in the past few hours but there are still some problems. The professional side also seems to be suffering as well, with several performance issues effecting a variety of services. If you are one of those currently suffering, you can follow the link from The Register to report it on Down Detector, if you wish.
"Naturally, users of Microsoft's cloud services have taken to Twitter and Reddit to moan about the downtime, with some complaining that Xbox online services have also been hit by the downtime."

Tagged: SoC, server, ryzen, opteron, Naples, HPC, amd
Over the summer, AMD introduced its Naples platform which is the server-focused implementation of the Zen microarchitecture in a SoC (System On a Chip) package. The company showed off a prototype dual socket Naples system and bits of information leaked onto the Internet, but for the most part news has been quiet on this front (whereas there were quite a few leaks of Ryzen which is AMD's desktop implementation of Zen).
The wait seems to be finally over, and AMD appears ready to talk more about Naples which will reportedly launch in the second quarter of this year (Q2'17) with full availability of processors and motherboards from OEMs and channel partners (e.g. system integrators) happening in the second half of 2017. Per AMD, "Naples" processors are SoCs with 32 cores and 64 threads that support 8 memory channels and a (theoretical) maximum of 2TB DDR4-2667. (Using the 16GB DIMMs available today, Naples support 256GB of DDR4 per socket.) Further, the Naples SoC features 64 PCI-E 3.0 lanes. Rumors also indicated that the SoC included support for sixteen 10GbE interfaces, but AMD has yet to confirm this or the number of SATA/SAS ports offered. AMD did say that Naples has an optimized cache structure for HPC compute and "dedicated security hardware" though it did not go into specifics. (The security hardware may be similar to the ARM TrustZone technology it has used in the past.)
Naples will be offered in single and dual socket designs with dual socket systems offering up 64 cores, 128 threads, 32 DDR4 DIMMs (512 GB using 16 GB modules) on 16 total memory channels with 21.3 GB/s per channel bandwidth (170.7 GB/s per SoC), 128 PCI-E 3.0 lanes, and an AMD Infinity Fabric interconnect between the two processor sockets.
AMD claims that its Naples platform offers up to 45% more cores, 122% more memory bandwidth, and 60% more I/O than its competition. For its internal comparison, AMD chose the Intel Xeon E5-2699A V4 which is the processor with highest core count that is intended for dual socket systems (there are E7s with more cores but those are in 4P systems). The Intel Xeon E5-2699A V4 system is a 14nm 22 core (44 thread) processor clocked at 2.4 GHz base to 3.6 GHz turbo with 55MB cache. It supports four channels of DDR4-2400 for a maximum bandwidth of 76.8 GB/s (19.2 GB/s per channel) as well as 40 PCI-E 3.0 lanes. A dual socket system with two of those Xeons features 44 cores, 88 threads, and a theoretical maximum of 1.54 TB of ECC RAM.
AMD's reference platform with two 32 core Naples SoCs and 512 GB DDR4 2400 MHz was purportedly 2.5x faster at the seismic analysis workload than the dual Xeon E5-2699A V4 OEM system with 1866 MHz DDR4. Curiously, when AMD compared a Naples reference platform with 44 cores enabled and running 1866 MHz memory to a similarly configured Intel system the Naples platform was twice as fast. It seems that the increased number of memory channels and memory bandwidth are really helping the Naples platform pull ahead in this workload.
AMD further claims that its Naples platform is more balanced and suited to cloud computing and scientific and HPC workloads than the competition. Specifically, Forrest Norrod the Senior Vice president and General Manager of AMD's Enterprise, Embedded, and Semi-Custom Business Unit stated:
“’Naples’ represents a completely new approach to supporting the massive processing requirements of the modern datacenter. This groundbreaking system-on-chip delivers the unique high-performance features required to address highly virtualized environments, massive data sets and new, emerging workloads.”
There is no word on pricing yet, but it should be competitive with Intel's offerings (the E5-2699A V4 is $4,938). AMD will reportedly be talking data center strategy and its upcoming products during the Open Compute Summit later this week, so hopefully there will be more information released at those presentations.
(My opinions follow)
This is one area where AMD needs to come out strong with support from motherboard manufacturers, system integrators, OEM partners, and OS and software validation to succeed. Intel is not likely to take AMD encroaching on its lucrative server market share lightly, and AMD is going to have a long road ahead of it to regain the market share it once had in this area, but it does have a decent architecture on its hands to build off of with Zen and if it can secure partner support Intel is certainly going to have competition here that it has not had to face in a long time. Intel and AMD competing over the data center market is a good thing, and as both companies bring new technology to market it will trickle down into the consumer level hardware. Naples' success in the data center could mean a profitable AMD with R&D money to push Zen as far as it can – so hopefully they can pull it off.

When Michael Abrash moved from Intel to Valve, according to his post on the latter company’s blog, he suggested that he should help optimize Portal 2. The response from Jay Stelly was interesting: “Yeah, you could do that, but we’ll get it shipped anyway.” That’s... not something you’d expect from a company that is getting ready to ship a huge, AAA title.
He took that feedback as a license to think outside the box, which led to their “wearable computing” initiative that eventually formed the basis of Steam VR. One key part of this blog post was the minor parenthetical, “think Terminator vision”.
Apparently, Microsoft’s HoloLens team has. As a cute little Unity demo, they are overlaying text and post-processing shaders atop the camera feed. It’s not just baked 2D text, though; they are also pushing the feed through object- and text-recognition, suggesting that users take the source (available on GitHub) and extend it through translation or text-to-speech.
The demo is primarily written in C#, which makes sense, because Unity.

A few months ago, just before Christmas in fact, we reported that Crytek was in the process of shutting down five out of their seven studios. Now, Sega has just announced that they are picking up one of them: Crytek Black Sea (Sofia, Bulgaria). This studio will be added to Creative Assembly, which makes the Total War series and also dipped its toe into the first person market with Alien: Isolation. As a part of this agreement, the ex-Crytek developer will now be called Creative Assembly Sofia.
Black Sea Studios was with Crytek since July, 2008.
As far as I can tell, the other four studios that were affected by December’s decision have not been as fortunate. Apart from ex-Rockstar designer, Leslie Benzie, picking up former employees of the Budapest, Hungary studio, I haven’t seen much talk about any other studio (or significant portions of them) moving elsewhere.

Logitech G has announced the new Pro Mechanical Gaming Keyboard, which features a compact tenkeyless (TKL) design, short-throw mechanical switches, and RGB lighting effects.
In addition to the TKL form-factor the Logitech G Pro Mechanical Gaming Keyboard features the company's exclusive Romer-G switches, which Logitech says "register key presses up to 25 percent faster than standard mechanical switches" and have "a short-throw actuation point 1.5 mm".
The keyboard also features keyboard durable construction with a steel back plate, and the cable is actually is a detachable micro-USB design, though not your typical micro-USB connector as this implementation features a wide three-pronged connection with support arms. Naturally, there are (optional) RGB effects for those who want them, which can be controlled via Logitech Gaming Software.
These RGB effects are per-key, which means seemingly endless levels of customizaiton considering each one can be set to one of "more than 16.8 million colors" and preferences saved to the onboard memory.
As to pricing and availability, the Logitech G Pro Mechanical Gaming Keyboard should be available later this month with an MSRP $129.99.

Just prior to the release of Tom Clancy’s Ghost Recon Wildlands, AMD has released another graphics driver with specific optimizations. Radeon Software Crimson ReLive Edition 17.3.1 is support to provide up to a 6% performance improvement (on an RX 480) in that title. It also adds a CrossFire profile under DirectX 11. Note that there’s a known issue with 3- and 4-GPU systems, which will apparently make the game crash back to desktop on launch.
Beyond this, the new graphics driver also fixes several issues, many of which involve flickering textures, objects, or mouse pointers. It also solves an issue where installing the driver could cause a failed reboot.
If you have an AMD GPU, then you can pick up the driver from their website.

Our own Sebastian Peak has delved into the nightmare world of testing WiFi, specifically MU-MIMO and explained some of the difficulties you encounter when testing wireless networks. It is now Ars Technica's turn to try to explain why your 2.4GHz router never delivers the advertised 1,000 Mbps as well as how to test your actual performance. As with many products, the marketing team has little interest in what the engineers are saying, they simply want phrases they can stick on their packaging and PR materials. While the engineers are still pointing out that even the best case scenarios involving a single user less than 10 feet away, with clear line of sight will not reach the theoretical performance peak, the PR with that high number has already been emailed and packages are printing.
Drop by Ars Technica for a look at how the current state of WiFi has evolved into this mess, as well as a dive into how the new technologies work and what performance you can actually expect from them.
"802.11n was introduced to the consumer public around 2010, promising six hundred Mbps. Wow! Okay, so it's not as fast as the gigabit wired Ethernet that just started getting affordable around the same time, but six times faster than wired Fast Ethernet, right? Once again, a reasonable real-life expectation was around a tenth of that. Maybe. On a good day. To a single device."

While mouse and keyboard is awesome for many games, a few benefit from the layout of a gamepad (or the way it’s used). There was a drought in these for a few years, particularly around the ~2007 time-frame, but this console generation provides us PC gamers with quite a few competent options. When they launched, both the PS4 and the Xbox One allowed their controllers to be used on the PC, and both eventually provided wireless adapters to make it function. Microsoft did it for Windows 10, and Sony did it for PlayStation Now. Even Valve got their Steam Controller out there, which is definitely an alternate alternative, like it or hate it. Personally, I’ve never tried.
While Nintendo hasn’t really ever supported the PC market, apart from, like, Mario is Missing, their Bluetooth-based controllers also never really tried to block PCs from using them. Apparently, the Nintendo Switch is no exception, and its Pro Controller seemingly just connects with the old gamepad API.
This isn’t supported, so it’s probably best to not go out and buy it for the PC, but feel free to try it if you already have a Switch and Pro Controller (and a Bluetooth adapter for your PC).

The Raspberry Pi Foundation recently introduced a $10 Pi Zero W which resembles the $5 single board Pi Zero computer it launched in 2015 but adds built in Wi-Fi and Bluetooth radios.
At the heart of the Raspberry Pi Zero W is a 1GHz single core Broadcom BCM2835 application processor and 512MB of RAM. Storage is handled by s micro SD card slot. The tiny board includes the following I/O options:
- 1 x Mini HDMI
- 1 x Micro USB OTG
- 1 x Micro USB for power
- 1 x 40-pin HAT compatible header
- 1 x CSI camera connector
- 1 x Composite video header
- 1 x reset header
The Pi Zero W uses the same Cypress CYW43438 chip as the Pi 3 Model B and offers 802.11n Wi-Fi and Bluetooth 4.0. According to the Raspberry Pi Foundation, they found that many users were using USB wireless dongles along with a HID (keyboard/mouse) and they needed to carry around a hub or integrate it into their project. Adding built in wireless frees up the single Micro USB port for ither devices and hopefully allows smaller devices that use a Pi Zero as its brains.
Per RasPi.TV’s testing, the new Pi Zero W uses approximately 20mA more power than the Pi Zero which the site attributes to the wireless radios. While it more power than the previous model it is still half that of the Raspberry Pi 3 B. Specifically, the Pi Zero W pulls 120mA at idle and up to 170mA when playing back a 1080p video. Recording 1080p video from a camera uses ~230 mA. The SBC is rated at 0.6W to 1.2W (120 to 230 mA at 5.19V).
A modular official case is being released alongside the new board. US residents will be able to pick up the $10 single board computer at Adafruit, CanaKit, and Micro Center.
The Pi Zero has been used in a large variety of projects including robotics, arcade games, home automation and motion sensing cameras IoT, information displays, and electric skateboards. Integrating the wireless radio should make similar projects just a bit easier to out together.

Tagged: netgear, Intel, Avoton, recall
While this is more useful for our readers in the IT field, NETGEAR has issued a (non-urgent) recall on sixteen models of Rackmount NAS and Wireless Controller devices. It looks like the reason for this announcement is to maintain customer relations. They are planning to reach out to customers “over the next several months” to figure out a solution for them. Note the relaxed schedule.
The affected model numbers are:
- WC7500 Series:
- WC7500-10000S, WC7500-100INS, WC7500-100PRS, WB7520-10000S, WB7520-100NAS, WB7530-10000S, WB7530-100NAS
- WC7600 Series:
- WC7600-20000S, WC7600-200INS, WC7600-200PRS, WB7620-10000S, WB7620-100NAS, WB7630-10000S, WB7630-100NAS
The Register noticed that each of these devices contain Intel’s Avoton-based Atom processors. You may remember our coverage from last month, which also sourced The Register, that states these chips may fail to boot over time. NETGEAR is not blaming Intel for their recall, but gave The Register a wink and a nudge when pressed: “We’re not naming the vendor but it sounds as if you’ve done your research.”
Again, while this news applies to enterprise customers and it’s entirely possible that Intel (if it actually is the Avoton long-term failure issue) is privately supporting them, it’s good to see NETGEAR being honest and upfront. Problems will arise in the tech industry; often (albeit not always) what matters more is how they are repaired.
